Reaktionsschritte
p-Toluenesulfonic acid hydrate (40 mg) and epifluorohydrin (0.15 mL) [CAS No.503-09-3] were added to a solution of N-cyclopropylmethyl-N-[7-(2-methoxy-4,6-dimethylphenyl)-2-(methylsulfanyl)pyrazolo[1,5-a]pyridin-3-yl]amine (50 mg) in 1,2-dimethoxyethane (0.40 mL), and the mixture was heated to reflux for 3 hours. After cooling to room temperature, the solvent was distilled off under reduced pressure. The obtained residue was purified by basic silica gel column chromatography (ethyl acetate:n-hexane=1:5) to obtain the title compound (24 mg) as a brownish oil.
